JFP - High Voltage Metallized Polypropylene Capacitor Drawing

About Film Capacitors

Plastic film capacitors are insulated with polyester, polypropylene, polystyrene or other dielectric materials. Polyester film capacitors offer a high dielectric constant and high dielectric strength. Metallized polyester film capacitor provides excellent self-healing properties, allowing capacitors to withstand high-pulsed voltages without breaking the dielectric. Polypropylene film capacitors provide very low loss, low dielectric absorption, and high dielectric strength. They also offer very high insulation resistance and negative temperature coefficient. Polystyrene film capacitors provide extremely low losses, low dielectric absorption, good long-term stability, very high insulation resistance and a small negative temperature coefficient.
